5 wrestlers Roman Reigns is yet to face in WWE

#4 Matt Hardy

A match between Matt Hardy and Reigns would not be far away

Matt Hardy made his return to WWE last year at WrestleMania 33. Since then, he and Reigns have not crossed each other's paths.

Hardy, with his "woken" gimmick, is feuding with Bray Wyatt whereas The Big Dog has his eyes set on the Universal Championship.

With both the wrestlers on the same brand, a match between them might not be too far. Hardy has been associated with WWE for around two decades, and the creative should certainly book a feud between the two. That would be wonderful.
